Fluids change over time and the shifting chemical composition can itself cause air bubbles to form. Whilst perfectly capable of doing the job it was selected for at the research and development stage, multiplying that many times over to get to full capacity (e.g 1 part/day produced vs 100 parts/day produced) can often lead to a number of problems including the production of air bubbles. (Regarding the latter, I've also read from this source that it has to do with the gas filling up the vacuume that is created when the knuckles are stretched. Soft tissue provides padding and protection. Chemical tests to check for changes in the fluid's chemicals. Often overlooked, but something to consider when other lines of enquiry have been pursued is whether fluids are reacting with any wetted parts to create gas bubbles?
